sorry for bringing up an old topic but this sounds exactly like mine but my car is an r34 and its really bad. just wondering where you got the nismo muffler from and when in first gear did your car shudder a little bit when u accelerate but if u do it soft it is fine.

I got the NISMO cat back from Just Jap. Any old muffler or cat back system will eliminate the nasty resonating

Umm.. by shuddering, Im not sure if this is a driveline problem, more so than a engine.

But I have noticed if I am in 1st, and only just creeping along I.e a carpark, it will jolt, but its not a jolt as in "you dont have enough RPM" jolt. It seems like the clutch is slipping. As soon as eve ret my foot on the gas, it completely disapears.

Im kind of doubtfull its an engine issue and not a driveline issue.

As for your engine, the r34 RB25DE with VVT and my Rb25DE with VCT has a different cams opperating system.

Not sure if this answers anything, but feel free to ask more questions if needed.

Cris,

WOOO! MY THREAD DID HELP!

probably just need more revs? like border-line stalling...?

correct; both cams on the neo rb25 have variable timing.

thanks for your help guys. to explain it a little bit better in first gear if i take off really soft its fine but if i put my foot down a little bit more and it revs into the zone where you hear that horrible noise it vibrates a fair bit and then its fine, so hopefully its just that sound making it act like that.

      M35 Brake caliper replacement

      By Waders360 · Posted

      Hi from Canada, Both of my calipers are starting to fail. My car is a 2005 M35 Stagea ARX and I can't seem to find any parts or any cross reference caliper that would fit my car. Is there a company or a similar caliper that would fit and I could replace the OEM one. Or if anyone knows where I can find a new OEM. Any help is very appreciated. Let me know!

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

      My BMW E39 528i touring

      What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.
